It was bound to happen. Kentucky’s annually freshman-laden team would play like neophytes and walk out of Rupp Arena losers.

On Saturday, for the first time in John Calipari’s four-year tenure, Kentucky lost a home game.

Baylor, with four key players from last spring’s Elite Eight squad leading the way, stunned No. 8 Kentucky 64-55 to snap the Wildcats’ 55-game home win streak.

“This one means a lot with them knocking us out of the Elite Eight,” Baylor point guard Pierre Jackson told CBS Sports. “I kind of took it personal to come out here and win, but they gave us a great game.

“The big thing was trying to keep this crowd out of it because they really get this team focused.”

Baylor shot the ball better, converted turnovers into points more efficiently and was bolstered by a few clutch 3-pointers by veteran guards Jackson, Brady Heslip and A.J. Walton to thwart UK momentum.

“We sleep better every night knowing that at the end of games we have veterans out there,” Baylor coach Scott Drew said. “Let’s start with Pierre Jackson. He’s a winner and he cares about the right things.”

Kentucky, which relies on four freshmen and has only one player returning from its rotation that won last season's national title, mostly worked for good shots Saturday but struggled to convert. UK shot only 29.2 percent from the field and 50 percent at the free-throw line.

"That's what happens when you have a bunch of freshmen out there," Calipari said.

With Kentucky losing, Long Island-Brooklyn now holds the nation’s longest home win streak at 28 games heading into its home game against Columbia later Saturday. Kansas (26 games), Syracuse (25) and South Dakota State (20) are next in line.

Heslip, playing just 10 days after an emergency appendectomy, hit only two 3-pointers but his presence on the court often distorted UK’s defense and allowed teammates better looks. A career 44.5 percent 3-point shooter, Heslip scored 10 points. Jackson led Baylor with 17 points, five assists and four steals. Walton and center Isaiah Austin added 11 points apiece, and Cory Jefferson added 10.

The young Wildcats, who now have lost two in a row, don’t have much time to lick their wounds or do soul searching. They play host to Samford on Tuesday.

"They came in here and executed what they were supposed to be doing," Kentucky freshman center Willie Cauley-Stein said. "I gave them credit for that. We shot ourselves in the foot. We didn't make shots and gave up easy plays that could have helped us in the end."

Kentucky especially struggled with Baylor's zone and athleticism.

"I would say it's us not going out there and trying to beat them as bad as they want to beat us," Goodwin said. "Every game that we are going into they are looking to try to come at our heads the hardest because of the name across our chests. As a team we don't go back at them the same way."
